fix(qemu): remove validate_ns_entrypoint

Browse source 
QEMU has dynamic memory configuration based on -m parameter. The
hard-coded values in TF-A are not accurate when starting the model with
this parameter. This is not a problem when loading boot images as the
lower addresses are the same. However, it can be a problem when starting
up the secondary CPUs with a rather high non-secure entry point. So fix
this by removing the plat_psci_ops_t validate_ns_entrypoint assignment
to allow any non-secure entry point.
